Can someone tell me if this header and this catalytic converter will fit?

[FiberOptixx]

I need to get a new header, catalytic converter, and cat back. I have already picked out my cat back, so now i need to figure out if the header will fit on the cat. It says on the header that the inlet/outlet is 1.75"/2.0" and on the catalytic converter it says its inlet is 2.25" and outlet is 2.5". So just let me know if they will fit the pictures/website of them is below. My car is a 92 integra.
